There are a minimum amount of characters required in a post and a maximum number of characters allowed in a post. If you are under or over, when you click "submit reply" you will instantly see a message stating your post is either too short or too long.
If you just try to post "Hi" or "Welcome" you would see the too short message.
Michelle, you now have a couple of welcomes and more may follow.
Attention: "role based name" email prefixes such as support, webmaster, info, contact, forum, service, affiliate, admin, traffic, partners, marketing, etc., for our member accounts are not permitted. They are acceptable for a vendor listing, but not for the member email. This is due to bulk email processors scrubbing them for delivery due to extremely high bounce rates. Please apply for membership using a personalized email prefix. Something like firstname.lastname@example.org.
If we discover you signed up with a role based name we will give you only one message to change it. After 3 days your account will be removed if the email is not changed.
